SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps identify complex security vulnerabilities and bugs in codebases by treating code as a database for deep analysis.

Core Features & Use Cases

  • Static Analysis: Performs interprocedural control flow and data flow analysis across entire codebases.
  • Vulnerability Detection: Prevents the introduction of known bugs and security vulnerabilities.
  • Use Case: A security engineer can use CodeQL to find subtle vulnerabilities like unhandled error return values or potential buffer overflows in a C++ project that simpler tools might miss.

Quick Start

Use the codeql skill to create a database for the current C++ codebase.

FAQPage Schema
What is deep static analysis and how does it find security vulnerabilities?▼

Deep static analysis identifies security vulnerabilities by treating code as a queryable database. It performs interprocedural control flow and data flow analysis across entire codebases to expose subtle bugs simpler tools miss.

How do I run data flow analysis on a C++ codebase to check for bugs?▼

Run data flow analysis on a C++ codebase by using the CodeQL CLI to create a database from your build process, then querying that database to expose interprocedural security vulnerabilities and bugs.

Does static code scanning with CodeQL work with Python and JavaScript?▼

Yes, static code scanning supports multiple languages including Python, JavaScript, C/C++, and Java. It performs interprocedural control flow and data flow analysis across these codebases to detect vulnerabilities.

Do I need to build my codebase before creating a database for vulnerability detection?▼

Yes, vulnerability detection requires building the target codebase. The CodeQL CLI needs a successful build process to extract the interprocedural control flow and data flow relationships necessary for database creation.

What are the limitations of using CodeQL for security analysis?▼

A primary limitation of CodeQL security analysis is the strict requirement for a buildable codebase. If the target code cannot be successfully compiled, the CodeQL CLI cannot extract the necessary data flow relationships to create the analysis database.
